The wonderful thing about the talking dog collars in 'UP' is that we were able to hear the thoughts of the dogs without moving their mouths or emoting like a human. The dogs could pant, scratch, and move the way dogs truly do. The animators studied the movements of many dogs, and we had a dog specialist come in and talk to us about dog behavior.
